일반적으로 농촌에는 겨울의 추운 날씨로 인해 농작물을 경작할 수 없어 일손을 놓고 쉬는 경우가 많았는데, 이러한 농한기에도 각종 채소나 과일 등의 경작이 이루어지게 함으로써 소득을 올리기 위해 제안된 비닐하우스로 인하여 계절에 관계없이 원하면 어느 때든 상기의 채소나 과일 등을 공급할 수 있도록 하고 있다.Generally, in rural areas, cold weather in the winter can not cultivate the crops. In such a case, the vegetable and fruits are cultivated in the farming season. The user can supply the above-mentioned vegetables or fruits at any time.

이에 통상의 비닐하우스는 도 1에서 보는 바와 같이, 아치형으로 형성되는 메인프레임(10)이 나열되고, 상기 메인프레임(10)의 상단부에 메인프레임을 고정 및 지지하기 위한 보강프레임(20)이 결합되며, 이러한 프레임 골격 위에 비닐하우스용 필름(30)을 설치한 후, 필름의 양단부를 흙속에 묻어 고정시키거나 또는 밴드나 접착제와 같은 별도의 고정수단에 의해 프레임과 결착시키도록 형성된다.As shown in FIG. 1, the conventional vinyl house includes a main frame 10 arranged in an arcuate shape, and a reinforcing frame 20 for fixing and supporting a main frame to an upper end of the main frame 10 After the vinyl house film 30 is placed on the frame skeleton, both ends of the film are formed to be fixed to the soil by being buried in the soil or by a separate fixing means such as a band or an adhesive.

그러나, 상술한 비닐하우스용 필름은 제조공정이 복잡할 뿐만 아니라, 주필름 부분이 손상될 경우, 이를 수리하기 위해 부필름 부분을 다시 제거하여야 하는 번거로움이 발생되었고, 비닐필름 자체의 내구성이 기존의 필름과 별다른 차이가 없어 외력에 의한 손상이 빈번하게 발생되는 문제점이 있었다.
However, the above-mentioned vinyl house film is not only complicated in manufacturing process, but also troublesome to remove the sub-film portion in order to repair the main film portion when the main film portion is damaged, and the durability of the vinyl film itself And there is a problem that damage due to external force frequently occurs.

FIG. FIG. 5 is a flowchart showing a method of manufacturing a film having a double structure for a vinyl house containing carbon nanotubes according to the present invention. FIG. 5 is a sectional view showing one embodiment of a film having a double structure for a vinyl house.

먼저 본 발명은 크게 내피(100)와 외피(200) 및 공기층(300)으로 구성된다.First, the present invention mainly comprises an inner skin 100, an outer skin 200, and an air layer 300.

이때, 도 2에서 보는 바와 같이, 상기 내피(100)는 폴리계열수지의 조성물(110) 100중량%에 대하여 탄소나노튜브(CNT)분말(120)이 10 내지 50중량%의 비율로 혼합되어 필름의 내구성 및 공극(air gap)을 형성하여 단열성을 도모하도록 형성된다.2, the endothelium 100 is mixed with carbon nanotube (CNT) powders 120 at a ratio of 10 to 50% by weight based on 100% by weight of the composition 110 of the poly-based resin, Durability and air gaps are formed to provide heat insulation.

이때, 상기 탄소나노튜브 분말(120)의 적정량은 10 내지 50중량%가 혼합되는 것이 적당하였으며, 특히 20 내지 40중량% 정도로 혼합되는 것이 바람직하다.At this time, the appropriate amount of the carbon nanotube powder 120 is suitably 10 to 50% by weight, particularly 20 to 40% by weight.

즉, 탄소나노튜브 분말이 10중량% 이하일 경우 필름의 내구성이 일반 폴리계열수지 필름과 비교하여 차이가 없었으며, 또한, 탄소나노튜브 분말이 50중량% 이상일 경우에는 내구성면에서는 크게 향상되었으나, 필름의 탄성이 저하되어 비닐하우스의 설치에 적합하지 않은 단점이 발생되어 바람직하지 않았다.That is, when the carbon nanotube powder is 10 wt% or less, the durability of the film is not different from that of the general poly-based resin film. When the carbon nanotube powder is 50 wt% or more, So that it is not suitable for installation of the vinyl house, which is not preferable.

이러한 내피(100)는 기존의 비닐 필름에 비하여 내구성이 보강될 뿐만 아니라, 폴리계열수지의 조성물(110)과 탄소나노튜브 분말(120)의 사이에 공극(air gap)이 형성되어 보온 및 단열효과가 개선되는 장점이 있으며, 눈, 비, 바람 등과 같은 외부환경에 대한 파손 및 변형을 최소화 할 수 있는 장점이 있다.The inner film 100 is reinforced in durability as compared with the conventional vinyl film and an air gap is formed between the composition 110 of the poly-based resin and the carbon nanotube powder 120, There is an advantage that damage and deformation to the external environment such as snow, rain, wind and the like can be minimized.

또한, 도 3에서 보는 바와 같이, 상기 외피(200)는 폴리계열수지로 형성되며, 상기 내피(100)의 면상에 단열성을 보강하도록 고주파융착에 의해 접착되어 필름을 형성한다.3, the envelope 200 is formed of a poly-based resin, and is adhered to the surface of the inner film 100 by high-frequency welding so as to reinforce the heat insulating property, thereby forming a film.

이때, 상기 필름은 도 4에서 보는 바와 같이, 내피(100)와 외피(200)사이에 공기층(300)이 형성되도록 내,외피의 접착 시 설정된 부분만을 고주파융착에 의해 접착되어 이루어진다.At this time, as shown in FIG. 4, the film is adhered by high-frequency welding only a predetermined portion of the inner and outer shells 100 and 200 when the inner and outer shells 100 and 200 are bonded.

즉, 내피(100)의 공극으로 인한 1차적인 단열효과에 부가적으로 내피(100)와 외피(200)의 사이에 엠보싱 형태와 같은 공기층(300)을 형성하여 2차적인 단열효과를 부가하여, 겨울철에도 비닐하우스 내부의 온도를 일정하게 유지할 수 있도록 하기 위함이다.
That is, in addition to the primary heat insulating effect due to the pores of the inner skin 100, an air layer 300 such as an embossed form is formed between the inner skin 100 and the outer skin 200 to add a secondary heat insulating effect , So that the temperature inside the vinyl house can be kept constant even in winter.

한편, 본 발명에 따른 탄소나노튜브가 함유된 비닐하우스용 이중구조를 갖는 필름의 제조방법은 다음과 같다.The method for producing a carbon nanotube-containing film having a double structure for a vinyl house according to the present invention is as follows.

먼저, 폴리계열수지의 조성물 100중량%에 10 내지 50중량%의 비율로 탄소나노튜브 분말을 혼합하는 혼합단계(S100)이다.First, the mixing step (S100) of mixing the carbon nanotube powder at a ratio of 10 to 50% by weight to 100% by weight of the composition of the poly-based resin.

이때, 상기 탄소나노튜브 분말(120)의 적정량은 10 내지 50중량%가 혼합되는 것이 적당하였으며, 특히 20 내지 40중량% 정도로 혼합되는 것이 바람직하다.At this time, the appropriate amount of the carbon nanotube powder 120 is suitably 10 to 50% by weight, particularly 20 to 40% by weight.

다음은, 상기 혼합된 조성물을 고온 및 고압의 압출기를 이용하여 내피(100)를 압출하는 압출단계(S200)이다.Next, the mixed composition is extruded (S200) by extruding the endothelium 100 using a high-temperature and high-pressure extruder.

이때, 상기 압출기는 당업계에서 쓰이는 통상의 압출기면 충분하며, 압출된 내피(100)가 외피(200)가 접착하기 위한 별도의 접착다이스로 이송되는 것이 바람직하다.At this time, it is preferable that the extruder is a conventional extruder used in the related art, and the extruded endotheliquid 100 is transferred to a separate adhesive die for adhering the outer skin 200.

다음은, 상기 압출된 내피(100)와 폴리계열수지로 형성된 외피(200)를 정렬한 후, 고주파융착에 의해 내,외피가 접착되어 필름 원단을 제조하는 접착단계(S300)이다.The following is an adhering step (S300) of aligning the extruded endothelial sheet 100 and the outer skin 200 formed of a poly-based resin, and then adhering the inner and outer envelopes by high frequency welding to produce a film end.

이때, 상기 접착단계(S300)는 내피(100)와 외피(200) 사이에 공기층을 형성하도록 설정된 부분만을 고주파융착에 의해 접착하도록 하는 부분접착단계(S310)가 더 포함되는 것이 바람직하다.In this case, it is preferable that the adhering step S300 further includes a partial adhering step (S310) for adhering only the portion set to form the air layer between the inner film 100 and the outer film 200 by high frequency welding.

즉, 도 4에서 보는 바와 같이, 설정된 부분을 접착하여 내피(100)와 외피(200) 사이에 공기층(300)이 형성되도록 함으로써, 필름의 단열성을 개선하여 비닐하우스 내부의 온도를 유지할 수 있도록 하기 위함이다.That is, as shown in FIG. 4, the air layer 300 is formed between the inner film 100 and the outer film 200 by adhering the set portions, thereby improving the heat insulating property of the film so as to maintain the temperature inside the vinyl house. It is for this reason.

마지막으로, 상기 접착된 필름 원단을 권취 또는 롤링하도록 하는 마감단계(S400)이다.Finally, it is a finishing step (S400) in which the bonded film fabric is wound or rolled.

이러한 본 발명은 탄소나노튜브가 함유된 내피와 폴리수지계열의 외피가 결합되어 내구성 및 단열성을 크게 향상시켜 계절의 변화나 눈,비 또는 바람과 같은 외력에 대한 저항력을 개선함은 물론, 기존 비닐하우스의 투광성을 유지할 수 있는 장점이 있다.In the present invention, the endothelium containing carbon nanotubes and the polyvinyl resin-based sheath are combined with each other to improve durability and heat insulation property, thereby improving seasonal changes, resistance to external forces such as snow, rain or wind, There is an advantage that the light transmittance of the house can be maintained.

또한, 필름의 내피와 외피 사이에 단열성을 더욱 보강하도록 하기 위해 공기층을 형성함으로써, 외부기온과 상관없이 비닐하우스 내의 온도를 일정하게 유지할 수 있도록 하여 작물의 성장에 필요한 최적의 환경을 제공할 수 있는 효과가 있다.
In addition, by forming an air layer so as to reinforce the heat insulating property between the inner and outer surfaces of the film, it is possible to maintain the temperature in the greenhouse constant regardless of the external temperature to provide an optimum environment necessary for growing the crop It is effective.

본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
